EDWIN A. HOWE, OF BANCROFT, IOWA.

AUTOMOBILE-TIRE.

Specification of Letters Patent. Application filed February 21, 1913.

To all whom it may concern.

Be it known that I, EDWIN A. Howe, a citizen of the United States,residing at Bancroft, in the county of Kossuth, State of Iowa, haveinvented certain new and useful Improvements in Automobile-'lires; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in tires, and particularly tocushion tires.

One object of the invention is to provide a cushion tire as a whole,which can be easily applied to the ordinary automobile wheel rim.

Another object resides in the peculiar construction and arrangement ofparts to produce resiliency and to protect the parts from dirt and dust.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of a portion of a tire made inaccordance with my invention. Fig. 2 is a vertical longitudinalsectional view therethrough. Fig. 3 is a vertical transverse sectionalview on the line 3-3 of Fig. 2 and Fig. 1 is a detail view of theconnection of the outer rim.

Referring particularly to the accompanying drawings, 10 represents theinner or rim engaging band, which is formed preferably of two sectionsattached together, and formed with the upturned ends 11 which aresecured together by means of the bolts 12, these sections beingpreferably in the form of channels, said sections being secured to therim 13 by means of the bolts 14. Arranged outside of the rim engagingband 10 and concentric therewith is a band 15, this band being made upof a plurality of sections 16. Formed on the abutting ends of thesections 16 are the tongues 17 which are bent back on the sections toform loops, and are adapted to receive one end of a coil spring 18, theopposite end of which is bolted to the inner rim member 10. There are aplurality of these springs 18, which are arranged at the joints betweenthe members 16. Thus a portion of the spring forms a part of the hinge,the free end of the spring being formed with threads to receive a nut19. On the inner faces of the sections 16 and on the outer face of theinner band 10 are arranged loop members 20 through which are passed wirehoops 21, these hoops having secured thereto, by their marginal edges,the fabric guards 22, these being arranged on opposite sides of the tireand covering the spaces between inner rim 10 and the outer rim 15 toprevent dust and dirt entering between the rims. Mounted on the outerface of the rim 15 is a continuous metal band 23 provided with aplurality of points 21- to prevent skidding. The band 23 has flanges 25on its edges for engagement with the sides of the outer rim 15 toprevent the same moving laterally on the said rim.

That is claimed is:

A cushion tire comprising a rim engaging band, a band arrangedconcentrically outward of the rim engaging band, said outer band beingformed in sections, perforated lugs carried by the adjacent ends of thesections of the outer band, coil springs secured to the rim engagingband and having their opposite ends disposed through the perforated lugsto form hinges between the sections 01' the outer bands, and a treadmember mounted on the outer rim.

In testimony whereof, I atlix my signature, in presence of twowitnesses.

LOUIS I-IYVE, OF DORIGNIES, NEAR DOUAI, FRANCE.

SELF-ACTING CONVEYER FOR COAL AND GOAF-lACKING IN COLLIERY-INCLINES OFLOW GRADIENT.

Specification of Letters Patent.

atcntedNov. 18,1913.

Application filed October 15, 1912. Serial No. 725,851.

To aZZ whom it may concern:

Be it known that I, Louis Hrvn, a citizen of the French Republic,residing at Escarpelle Mines, Dorignies, near Doua'i, (NOICl,) France,have invented certain new and useful Improvements in Se.lt'-i .ctingConveyors for Coal and Goat-Packing in Colliery-Inclines of LowGradient, of which the following is a specification.

This invention. relates to the conveyance of coal, rubble and the like,and has for its object to provide an economical and etlicient apparatusfor conveying coal or the like along the sloping coal faces of thinseams of low gradient. It is particularly adapted for long wallcuttings.

The apparatus consists of a series 01" troughs which may be one meter inlength and of the construction described hereinafter.

In the accompanying drawing, Figure 1 is a side elevation, partly insection, oi. one length or section of the apparatus, Fig. 2 is a planview, partly in horizontal section; Fig. 3 is a vertical sectional viewtaken on the line A-A of Fig. 1; Fig. t is a vertical sectional viewtaken on the line B B of Fig. 1; Fig. 5 shows a vertical section on theline C0 of Fig. 2, and Fig. 6 shows a vertical section on the line Dl)of l ig. 2.

The apparatus is composed of a series of chutes the floor of which iscomposed of llat parts a between which project the upper part ofadjacent rollers b. The Hatparts a are cut beveled on their lateraledges adjacent to the rollers. The floors oil' the chutes are connectedend to end by the beveled edges 0/, b and the sides are connected byprojections 0 (Figs. 1 and 2).

The whole apparatus forms a regular series of flat parts a, and ofrollers b mounted on shafts o engaged in the bearings 21, carried by thelower prolongations d of the sides 6 of the chutes. Near the ends of theshafts o are provided lubricating holes closed by screws Z). The flatparts a are sustained by iron reglcts a the ends of which are in casedin the oak brackets t (Figs. 1, 4.). The sheet-iron floor and sideplatcsof the chutes are kept rigid by means of screw tierods r r, s, and thebrackets t, which almost conform to the shape of the rollers Z). Theshafts o are rigid with hubs mounted thereon which are connected to theinner faces of the rollers b by arms f which also serve to immobilizethe (.lesired rollers by the mampulation ot. the bolts .l, 2, 3, ilwhich can be engaged between the arms as shown by the dotted lines oi.Fig. 3. These bolts 1, 2, etc. are slidable longitudinally and rotatablein ferrules rigid with the side plates cl. The path of the sliding islimited in opposite directions by flanges it fixed on the bolts. Tueouter part oi these bolts is bent at a right angle and threaded at f soas to be capable oi. being fastened or not to the bars (6 0, that aremanipulated to free or to stop simultaneously all the rollers the boltsof which are ctmnectcd to these bars. The rollers b, which aredisengaged, turn under the weight 01" the coal and force the sliding onthe llat parts a.

lVhen desired the apparatus can give:

1. A continuous llow corresponding to a continuous loading, by apermai'lent disengagement oil a certain number of rollers b, which isapplicable to rising cuts. The disengagement of the rollers o isell'ected by drawing out the corresponding bolts 1, 2, 3, as shown byfull lines in Fig. 3.

2. An intermittent llow of the contents of the chute, by simultaneousdisengagement of a determined number of rollers I), which permit a rapidloading into cars at the bottom of the cut. in this case the apparatusis plOVltlOtl, to :urcclerate the manipulation, with rods (Z c piercedwith elongated openings Z permitting the engagement of the threaded partj of the correspoiuling bolts with the rollers Z) before being liberatedtogether.

All the bars (Z c of a series oi. three chutes, corresponding to aworkers position, can be connected by means of clamping screws g. InFig. 2 the bolts .1. and 2 only are connected to the bar (1 (2, theram-responding rollers 7) being disengaged; the others can bemanipulated separately and they are shown in inner position in thesleeves g, which corresponds to the position of disengagement of thecorrespoiuling rollers. To engage the rollers with the bolts 1,2, thebar (Z c is pushed in the direction of the arrow 7" (Fig. 2). At commandall the workers of the cut can operate their respective rods in thedirection of the arrow Zr, Fig. 2) to dis engage the rollers the boltsof which are connected to this rod and cause the descending movement.

The apparatus bounded by the lines h, z,

' radius of the rollers; and means for at will j, is, Z (Fig. 1) isapplied toseams of coal with an opening of 0.40 meter, that is to saythe smallest worked. For thicker seams the apparatus is provided withsides Z, m, n, h, of a height variable with the opening of the seam andfixed by means of bolts and pins 7), (Figs. 1 and 3).

In operation, a practical precaution is first to load the larger lumpson the base of the chute and the smaller on top. Cut-away places a, j,76, arranged at the base of the prolongations d, permit the easywithdrawal of the small particles which may pass beneath the floor. Eachchute is provided With two handles Z at each end. In a rising cut, themanipulation of the additional chutes is effected by means of a smallWheeled truck carrying the chute and for rails using the upper edges Z,h (Fig. 1) of the chutes already in position.

I claim:

1. In automatic chutes for conveying coal and the like in slightlysloping cuts, the combination of a series of closely placed rollershaving their axes disposed in sub stantially the same plane; flat stripsbetween said rollers and having beveled edges almost in contact with therollers, said rollers projecting above the strips a very small distancerelative to the length of the holding certain. of the rollersstationary.

2. In automatic chutes for conveying coal 1 and the like'in slightlysloping cuts, the

combination of a series of closely placed rollers having their axesdisposed in substantially the same plane; fiat strips between saidrollers and having beveled edges almost in contact with the rollers,said rollers projecting above the strips a very small distance relativeto the length of the radius of the rollers; and means for at willholding certain of the rollers stationary, said means comprisingslidable bolts adapted to'cngage the rollers.

8. In automatic chutes for conveying coal and the like in slightlysloping cuts, the combination of a series of closely placed rollershaving their axes disposed in substantially the same plane; flat stripsbetween said rollers and having beveled edges almost in contact with therollers, said rollers projecting above the strips a very small distancerelative to the length of the radius of the rollers; means for at willholding certain of the rollers stationary, said means comprisingslidable bolts adapted to engage the rollers and means forsimultaneously operating a plurality of the bolts.

In testimony whereof I have affixed my signature, in presence of twowitnesses.
